Yep Looks like DNS propagation.
In lay terms, the whole of the internet hasn't 'noticed' that the site's moved. Some ISPs are faster at copping on than others - Eircom being one of the notoriously slow ones
DNS for me still resolves to the old site too - 212.147.150.18
The DNS is reporting a new IP

So I reckon it's Eircom being silly slow buggers as always
I used a wallpaper scraper and small trowel to level off the grout, and just ran the trowel edge down the semi-set grout.
When very nearly set, i ran a small screwdriver along the rail side then ran an old wagon with deep flanges down just to be sure
I've actually very pleased with how well the grooves came out
I'm delighted with it, I did a section in woodlands smooth it, which looked great too, but a tub of grout from woodies is pre-mixed, cheap, and comes in white, cream, grey and black off the shelf.
